+# KX-Bridge – Anycubic Kobra X Moonraker Bridge
+
+**Version:** 0.9.1-beta10
+**Status:** Public Beta – suitable for home users, feedback welcome
+
+KX-Bridge is a Moonraker-compatible HTTP/WebSocket bridge for the **Anycubic Kobra X** 3D printer. It allows you to control the printer through OrcaSlicer and other Moonraker-compatible software — no Klipper, no Raspberry Pi required.
+
+---
+
+## What's supported?
+
+- Printer status (temperature, progress, state)
+- File transfer and print start
+- Print control: pause, resume, cancel
+- Temperature control during an active print
+- Print speed (Silent / Normal / Sport)
+- AMS filament change (load / unload)
+- Light and fan control
+- Web UI with dashboard, temperature cards, axis control, and camera view
+- Settings and self-update directly in the browser (⚙ menu)
+- OrcaSlicer connection (Moonraker protocol)
+
+---
+
+## Requirements
+
+- Anycubic Kobra X on your local network, with **LAN mode enabled** (printer menu → enable LAN mode)
+- Printer MQTT credentials (→ see [Extracting credentials](#extracting-credentials))
+- Docker **or** Python 3.9+ **or** the pre-built Linux binary
+
+---
+
+## Quick start – Docker (recommended)
+
+```bash
+# 1. Start the bridge
+./start.sh
+```
+
+`start.sh` builds the Docker image automatically on first run and starts the bridge.
+
+```
+# 2. Open the web UI: http://BRIDGE-IP:7125
+#    → Settings (⚙) open automatically on first start
+#    → Enter your credentials (→ see Extracting credentials)
+
+# 3. In OrcaSlicer: add printer → "Moonraker" → http://BRIDGE-IP:7125
+```
+
+Check logs:
+```bash
+docker-compose logs -f
+```
+
+Stop:
+```bash
+docker-compose down
+```
+
+---
+
+## Quick start – Binary (Linux)
+
+```bash
+chmod +x kx-bridge
+./kx-bridge
+```
+
+Open the web UI: `http://localhost:7125`  
+→ Settings (⚙) open automatically and guide you through the initial setup.
+
+---
+
+## Quick start – Python directly
+
+```bash
+pip install aiohttp
+python kobrax_moonraker_bridge.py
+```
+
+Open the web UI: `http://localhost:7125`  
+→ Settings (⚙) open automatically on first start.
+
+---
+
+## Extracting credentials
+
+The MQTT credentials are printer-specific and are generated on first connection with AnycubicSlicerNext. The `extract_credentials` tool reads them from the memory of the running slicer.
+
+**Requirement:** AnycubicSlicerNext must be running and connected to the printer (printer status is shown).
+
+### Windows
+
+```
+extract_credentials.exe
+```
+
+### Linux
+
+```bash
+chmod +x extract_credentials
+./extract_credentials
+```
+
+### Output
+
+```
+[*] Process found: AnycubicSlicerNext.exe (PID 1234)
+[*] 1986 memory segments read (738.8 MB)
+[*] Analyzing ... 100% (739 MB)
+

+
+Enter the displayed values in the bridge settings:  
+Open web UI → **⚙ Settings** → fill in the fields → **Save & Restart**
+
+> If the result looks uncertain: `--verbose` shows all found candidates.
+
+All credentials are **processed locally only** — nothing is sent to external servers.
+
+---
+
+## Configuration (.env)
+
+```env
+PRINTER_IP=192.168.x.x       # Printer IP address
+MQTT_PORT=9883                # Default, do not change
+MQTT_USERNAME=userXXXXXXXX   # Starts with "user"
+MQTT_PASSWORD=XXXXXXXXXXXXXX  # ~15 characters, mixed case
+DEVICE_ID=xxxxxxxx...         # 32-character hex string
+MODE_ID=20030                 # Kobra X default
+```
+
+---
+
+## OrcaSlicer setup
+
+1. Add printer → **Anycubic Kobra X** (or generic Klipper printer)
+2. Connection type: **Moonraker**
+3. Host: `http://BRIDGE-HOST:7125`
+4. Test connection → should show "Online"
+
+---
+
+## Web UI
+
+The bridge serves a web interface at `http://BRIDGE-HOST:7125`:
+
+| Section | Function |
+|---------|----------|
+| Dashboard | Printer status, progress, temperature overview |
+| Temperatures | Set nozzle and bed temperature directly |
+| Motion | X/Y/Z movement, motor release |
+| Print Speed | Silent / Normal / Sport |
+| Fan / Light | Fan speed and work light |
+| AMS | Load / unload filament |
+| Camera | Live preview (if supported by printer) |
+| ⚙ Settings | MQTT credentials, poll interval, self-update |
+
+### Self-update
+
+The ⚙ menu in the web UI lets you check for new versions and update the bridge in place — no reinstallation needed. After the download the bridge restarts automatically with the new version.
+
+---
+
+## bridge.sh (Linux service manager)
+
+```bash
+./bridge.sh start    # Start bridge in background
+./bridge.sh stop     # Stop bridge
+./bridge.sh restart  # Restart
+./bridge.sh status   # Check status and port
+./bridge.sh log 50   # Show last 50 log lines
+```
+
+---
+
+## Printer states
+
+The bridge translates internal Kobra states into Moonraker-compatible states:
+
+| Kobra state | Meaning |
+|-------------|---------|
+| free | Ready |
+| printing / busy | Printing |
+| pausing / paused | Paused |
+| resuming / resumed | Resuming |
+| stopping / stoped | Stopping |
+| finished | Complete |
+| canceled | Cancelled |
+| failed | Error |
+
+---
+
+## Troubleshooting
+
+**Port 7125 already in use:**
+```bash
+./bridge.sh stop    # or: fuser -k 7125/tcp
+./bridge.sh start
+```
+
+**Invalid credentials / connection refused:**
+- Start AnycubicSlicerNext, connect to the printer, then run `extract_credentials` again
+- If the result looks uncertain: `extract_credentials --verbose` shows all candidates
+- Manually enter the correct candidate in `.env` and restart the bridge
+
+**Temperature changes are ignored:**
+- During an active print, temperature changes are sent via a separate channel — this is normal and the bridge handles it automatically.
+
+**Docker: Permission denied:**
+```bash
+sudo usermod -aG docker $USER
+# Log out and back in
+```
+
+**Docker: .env not found:**
+```bash
+# .env must be in the same directory as docker-compose.yml
+cp .env.example .env && nano .env
+```
+
+---
+
+## Logs
+
+```bash
+# Docker
+docker compose logs -f kx-bridge
+
+# Binary / Python
+tail -f /tmp/bridge.log   # when using bridge.sh
+```
+
+---
+
+## Security notes
+
+- The bridge binds to `0.0.0.0:7125` by default — use on your local network only
+- `.env` contains printer credentials — do not share publicly
+- The credentials are printer-specific and have no access to Anycubic cloud services

 ## Voraussetzungen

- Anycubic Kobra X im LAN-Modus (Drucker muss über LAN erreichbar sein, nicht nur über Anycubic-Cloud)
- PC, NAS oder Server im gleichen Netzwerk (Windows oder Linux)
- Docker oder Python 3.9+
- MQTT-Zugangsdaten des Druckers → [Schritt 1](#schritt-1-zugangsdaten-ermitteln)
+- Anycubic Kobra X im lokalen Netzwerk, mit aktiviertem **LAN-Modus** (Drucker-Menü → LAN-Modus einschalten)
+- MQTT-Credentials des Druckers (→ siehe [Credentials extrahieren](#credentials-extrahieren))
+- Docker **oder** Python 3.9+ **oder** direkt die Linux-Binary

 ---

-## Schnellstart
-
-### Schritt 1: Zugangsdaten ermitteln
-
-Die Bridge benötigt druckerspezifische MQTT-Zugangsdaten.
-
-> Wichtig: Der Drucker muss sich im LAN-Modus befinden. Nur wenn der Drucker direkt über LAN (nicht ausschließlich über die Anycubic-Cloud) erreichbar ist, können die Zugangsdaten ermittelt und die Bridge genutzt werden.
-
-Die Zugangsdaten werden mit `extract_credentials` aus dem laufenden AnycubicSlicerNext ausgelesen.
-
-Vorbereitung: AnycubicSlicerNext starten und mit dem Drucker verbinden (bis der Drucker-Status angezeigt wird).
-
-Windows:
-```
-extract_credentials.exe --write-env
-```
-
-Linux:
-```bash
-chmod +x extract_credentials
-./extract_credentials --write-env
-```
-
-Die Zugangsdaten werden automatisch in `.env` gespeichert.
-
-> Falls das Ergebnis unsicher wirkt: `--verbose` zeigt alle gefundenen Kandidaten. Den richtigen Wert manuell in `.env` eintragen.
-
---
-
-### Schritt 2: Konfiguration prüfen
+## Schnellstart – Docker (empfohlen)

 ```bash
-cp .env.example .env
-# .env öffnen und Werte kontrollieren
+# 1. Bridge starten
+./start.sh
+```
+
+`start.sh` baut das Docker-Image automatisch beim ersten Aufruf und startet die Bridge.
+
+```
+# 2. Web-UI öffnen: http://BRIDGE-IP:7125
+#    → Einstellungen (⚙) öffnen sich automatisch beim ersten Start
+#    → Zugangsdaten eintragen (→ siehe Credentials extrahieren)
+
+# 3. In OrcaSlicer: Drucker → "Moonraker" → http://BRIDGE-IP:7125
+```
+
+Logs prüfen:
+```bash
+docker-compose logs -f
+```
+
+Stoppen:
+```bash
+docker-compose down
 ```

 ---

-### Schritt 3: Bridge starten
+## Schnellstart – Binary (Linux)

-Option A – Docker (empfohlen):
-```bash
-docker compose up -d
-```
-Läuft im Hintergrund, startet automatisch nach Systemneustart.
-
-Option B – Linux Binary:
 ```bash
 chmod +x kx-bridge
 ./kx-bridge
-# Oder mit Service-Manager:
-./bridge.sh start
 ```

-Option C – Python direkt:
+Web-UI öffnen: `http://localhost:7125`  
+→ Einstellungen (⚙) öffnen sich automatisch und führen durch die Erstkonfiguration.
+
+---
+
+## Schnellstart – Python direkt
+
 ```bash
 pip install aiohttp
 python kobrax_moonraker_bridge.py
 ```

---
-
-### Schritt 4: OrcaSlicer-Profil installieren
-
-1. `kobra_x_orcaslicer_preset.zip` in OrcaSlicer importieren:
-   Datei → Konfigurationen importieren → ZIP auswählen
-2. Anycubic Kobra X als Drucker auswählen
+Web-UI öffnen: `http://localhost:7125`  
+→ Einstellungen (⚙) öffnen sich automatisch beim ersten Start.

 ---

-### Schritt 5: OrcaSlicer verbinden
+## Credentials extrahieren

-1. Drucker-Einstellungen öffnen
-2. Verbindungstyp: Moonraker
-3. Adresse: `http://IP-DES-BRIDGE-PC:7125` eintragen
-4. Auf "Test" klicken – bei erfolgreicher Verbindung erscheint eine Bestätigungsmeldung
+Die MQTT-Zugangsdaten sind druckerspezifisch und werden beim ersten Verbindungsaufbau mit dem AnycubicSlicerNext generiert. Das Tool `extract_credentials` liest sie aus dem RAM des laufenden Slicers aus.

---
+**Voraussetzung:** AnycubicSlicerNext muss gestartet und mit dem Drucker verbunden sein (Drucker-Status wird angezeigt).

+2. Verbindungstyp: **Moonraker**
+3. IP: `http://BRIDGE-HOST:7125`
+4. Verbindung testen → sollte "Online" anzeigen
+
+---
+
+## Web-UI
+
+Die Bridge stellt unter `http://BRIDGE-HOST:7125` eine Web-Oberfläche bereit:
+
+| Bereich | Funktion |
+|---------|----------|
+| Dashboard | Druckerstatus, Fortschritt, Temperaturübersicht |
+| Temperaturen | Nozzle und Bett direkt setzen |
+| Achsen | X/Y/Z-Bewegung, Motorfreigabe |
+| Druckgeschwindigkeit | Leise / Normal / Sport |
+| Lüfter / Licht | Lüfterdrehzahl und Drucklicht |
+| AMS | Filament einziehen / ausziehen |
+| Kamera | Live-Vorschau (falls Drucker unterstützt) |
+| ⚙ Einstellungen | MQTT-Zugangsdaten, Poll-Intervall, Self-Update |
+
+### Self-Update
+
+Über das ⚙-Menü in der Web-UI kann die Bridge auf neue Versionen prüfen und sich selbst aktualisieren — ohne Neuinstallation. Nach dem Download startet die Bridge automatisch mit der neuen Version neu.
+
+---
+
+## bridge.sh (Linux Service-Manager)

 ## Fehlerbehebung

-Port 7125 belegt:
+**Port 7125 bereits belegt:**
 ```bash
-./bridge.sh stop
+./bridge.sh stop    # oder: fuser -k 7125/tcp
 ./bridge.sh start
 ```

-Verbindungstest in OrcaSlicer schlägt fehl:
- Firewall prüfen: Port 7125 muss erreichbar sein
- Bridge-Log prüfen: `./bridge.sh log` oder `docker compose logs`
- Drucker-IP in `.env` korrekt?
+**Credentials ungültig / Verbindung abgelehnt:**
+- AnycubicSlicerNext starten, mit Drucker verbinden, `extract_credentials` erneut ausführen
+- Falls das Ergebnis unsicher wirkt: `extract_credentials --verbose` zeigt alle Kandidaten an
+- Den richtigen Kandidaten manuell in `.env` eintragen und Bridge neu starten

-Zugangsdaten werden abgelehnt:
- AnycubicSlicerNext starten, mit Drucker verbinden
- `extract_credentials --verbose` ausführen und alle Kandidaten prüfen
- Richtigen Wert manuell in `.env` eintragen, Bridge neu starten
+**Temperaturänderungen werden ignoriert:**
+- Während eines laufenden Drucks werden Temperaturänderungen über einen separaten Kanal gesendet — das ist normal und wird von der Bridge automatisch erkannt.

-Docker: Permission denied:
+**Docker: Permission denied:**
 ```bash
 sudo usermod -aG docker $USER
-# Neu einloggen, dann erneut versuchen
+# Neu einloggen
+```
+
+**Docker: .env nicht gefunden:**
+```bash
+# .env muss im gleichen Verzeichnis wie docker-compose.yml liegen
+cp .env.example .env && nano .env

 ## Sicherheitshinweise

- Alle Zugangsdaten werden ausschließlich lokal verarbeitet
+- Die Bridge bindet standardmäßig auf `0.0.0.0:7125` — nur im lokalen Netzwerk nutzen
+- `.env` enthält Drucker-Credentials — nicht öffentlich teilen
+- Die Credentials sind druckerspezifisch und haben keinen Zugang zu Anycubic-Cloud-Diensten
